Abstract
Shark liver oil is one of the sources of cellular energy and provides repair and restoration of damaged cells, and supports in protection of the body from the emergence of tumorous conditions. The Shark liver oil was tested orally at the dose of 1g/kg body weight, on gastric ulceration experimentally induced by water immersion (Swimming). The parameters considered to assess the anti-ulcer activity were percentage of ulcer, ulcer index, percentage of inhibition, pH, free acidity and total acidity. Pretreatment with the Shark liver oil resulted in a significant decreased of the ulcerated area and reduced pH, free acidity and total acidity.
